\r\n The goal of a coordinate system is a means of specifying the position of an object.\r\n For example, imagine a billiards table, and consider a ball on this table.\r\n Now, if someone asks you to specify the location of the ball, how would you do this?\r\n You could say — the ball is located in the lower half of the table.\r\n Or, it is near the left edge of the board.\r\n Or, the ball is located at the lower left corner of the table.\r\n None of these statements describe the position of the ball precisely.
\r\n Now, if you say — the ball is 18 inches away from the left edge, it gives\r\n a better idea of the location of the ball but\r\n still does not fix the position of the ball. However, if you say the ball\r\n is located at 18 inches from the left edge and 12 inches from the bottom edge, it completely\r\n specifies the location of the ball on the table. You may have noticed that the ball on the table can be located\r\n by specifying its distances from two perpendicular lines — the left edge of the table, and the bottom edge of the paper.\r\n This notion forms the basis of coordinate geometry.\r\n
\r\n The position of any object lying in a plane\r\n can be represented by its distance from two perpendicular axes (lines). These axes are called coordinate axes, and the distances from these two axes used in specifying the location of\r\n the object are called its coordinates.\r\n

\r\n Through this visually interactive illustration, students will be able to\r\n assess their understanding of the Cartesian coordinates of a point. \r\n The MagicGraph shows a point named P on the Cartesian plane. Your goal is to find the the two coordinates of the point on this plane.\r\n
\r\n\r\n Enter your answers for the x and y coordinates in the blue boxes labeled as x and y, respectively.\r\n Once done, simply tap on the icon to check your answer.\r\n To practice with a new point position, simply tap on the icon to shuffle the point position.\r\n
